What inspired this wish list request? Having to perform a task of "make combined data table" and re-creating a complex function multiple times to get the desired values. Also, is difficult to coach scientist on how to do this with their data and there is opportunity for the formula to be modified or entered incorrectly by mistake.
What is the improvement you would like to see? Custom formulas for summary statistics that can be created then used in Tabulate, Distribution, Summary, Graph Builder etc. It would be great if you could also use any of these formulas as column formulas with the option of By Variables.(ex. Col GCV(:Column 1, :By Variable Column))
Why is this idea important?
Increase efficiency; Avoid errors when re-entering formulas; Allow flexibility to add to the COTS based on need.
